As can be seen in these figures, in some regions, e.g. Boqrati, there is no unique
non-dominated solution. In the Boqrati region,

. In this situation no one solution can dominate the other one. In
such cases all non-dominated solutions are proposed and this is the main disad-
vantage of proposed approach, while it has several advantages such as simplicity
of calculations, the ability to consider inherent specification of agricultural activi-
ties. The attributes considered in this research can improve the success of locat-
ing and activity of ASCs. The non-dominated solutions for Kharaqan, Razan and
Sardrood-Sofla have been illustrated by red rectangular in Figs.

results of other districts can be seen in Appendix 3.
The position of selected solutions of Boqrati, Kharaqan, Razan and Sardrood-
Sofla have been shown in Figs.

to clarify the power of proposed multi
attribute decision making approach.
